4000 words! crappy excerpt (and i'm finally getting to the story, ha):

"yes, i am alive," said the robot. "and thank you for saving me. my name is Y.U.T.U. and i am the last remnant of an ancient lunar civilization, come to earth to warn you of grave danger."

"my name is enzo!" said enzo. "e-n-z-o."

"greetings E.N.Z.O," said YUTU. "you are the one who found me."

"yes," he said. "this is my sister phoenix and her friend addison."

"greetings PHOENIX and ADDISON." the robot clicked and whirred.

phoenix shook her head. "is this for real? this must be some kind of prank. there's got to be hidden cameras somewhere. or right inside the robot."

"it's way more sophisticated to be a prank," said addison. "that technology inside. way too advanced."

"you really think it's from the moon, then?" said phoenix. "there's no life on the moon!"

"you are correct," said YUTU. "there is no life on the moon-- not any more. but millennia ago, there was. a highly advanced civilization that lived far beneath the surface."
